GIS: Advantages and Disadvantages of GIS







Advantages of GIS:
  • Improve Organizational Integration - GIS  integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
  • GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.
  • A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.
  • GIS technology can be integrated into any enterprise information system framework.
  • More employment opportunity
Disadvantages of GIS:
  • Expensive software
  • Requires an enormous amount of data inputs to be practical for some tasks and the more data that is put in
  • The earth is round and geographic error is increased as you get into a larger scale.
  • GIS layers, may lead to costly mistakes when property agents interpret a GIS map, or engineer's design around GIS utility lines.
  • there is the failure to initiate or sustain the additional effort to fully implement GIS, however large the anticipated benefits might be.
